I make hand crafted pens on a lathe. Some woth hundreds of dollars. I have mammoth tusk from 10,000 years ago that I've made pens from. I also have 5,000 year old Irish Bog Oak wood that I have made pens from. I have all kinds of stuff like that, even a bench from the Wrigley Field outfield bleachers when they replaced them a few years ago. Just a hobby, but it's fun. Here is a picture of one of the Mammoth Tusk Ivory pens I made for a friend. It's a titanium gold Emperor pen dressed in Mammoth Ivory.
